I don't actually own one of these as they are way overpriced even at the new lower price.
But every screenshot I have seen show lots of hardware errors when mining.
Isn't that a sign that they are already overclocked way to high?
It could be a simple power supply issue as well, I plan to feed it power independently of the usb key.
"FOR SCIENCE"
You can only mine SHA256 coins btw, not other alts. As for this - the chips themselves run on <2v so it may be a regulator limit and supplying more amperage on the USB socket/5v line may not actually help at all.
Anyway, would anyone with one already care to read off the crystal speed? Also the voltage regulator part number would be interesting, voltage reading even better, and maybe a current reading of what is being pulled over the USB. Then we could work out exactly how much headroom we have. An unlimited current supply on the 5v might help if the regulator has a decent amount of headroom.
